These are quite common.

Some times yes and sometimes no. As to the safety it depends on the tower.
The old American Steel which is pretty skinny (bout a foot on a side) was
*relatively* strong when properly guyed. I've climbed a few of those to 90
fee, but that are a lot of them I wouldn't climb 40 feet.

There's nothing wrong with setting limitations. We all do at some level or
another.

NEVER climb a tower unless you know it's physical state and ratings.
I've made it most of the way to the top of some self supporting towers and
said, "that's far enough!" and went back down. If I'm not comfortable
climbing a tower, or if I have any doubts I don't do it.
Most of those old, skinny, unguyed towers with a TV antenna on top were
designed to put assembled on the ground, the antenna installed and then
stood up and attached to the house bracket. Not all were put up that way,
but ...
I'd like to find a couple of those old skinny HBX that I could put up as
verticals on 40 or 75 but I'd not climb them.
